Activated carbon from Acacia asak (Fabaceae) tree branches was prepared utilizing three-steps- process and H3P04, ZnCl2, H2S04, K2C03, Na0H and K0H as chemical activating agents. In addition to the elemental analysis of precursor materials, produced activated carbon (ATB-AC) was also analyzed for moisture content, ash content, pH value, bulk density, volatile matter, hardness, specific surface area (SBET), iodine number and pore volume. Results revealed that the quality of ATB-AC is well comparable to the available commercial activated carbon (CAC). The SBET was found to be in the order of ATB-AC1> ATB- AC2> ATB-AC4> ATB-AC6> ATB-AC3> ATB-AC5. All the produced ATB-AC demonstrated good MB (methylene blue) removal efficiency, whereas ATB-AC1 and ATB-AC2 (produced from H3P04, and ZnCl2) showed higher efficiency. It is concluded that the chemical activating agent has significant effect on produced AC keeping all other production parameters constant. Among the six studied chemicals, H3P04 and ZnCl2 produced AC exhibited high SBET surface area and MB uptake capacity.

“…This is one of the most important factors to evaluate the adsorption capacity of activated carbon. It is commonly known that comparatively more active sites are available on a wider surface, allowing the material to be promising for adsorption 52,53 . In the present work, the BET surface area and total pore volume of ACTG were obtained as 1270 m 2 /g and 0.673 cm 3 /g, respectively.…”

“…Another aspect was the rough and stacked surface of the activated carbon particles that resembles a “loose sponge.” 61 SEM of ACTG displays surface discontinuation triggered by the activating agent, Na 2 S 2 O 3 in this instance. The well‐developed porosity and consequent surface boost, with a surface area of 1270 m 2 /g, were preferably driven by the dehydration due to carbonization 52 . Flaky fragments at the magnification of 500 X were observed by Bardalai et al 60 The SEM micrograph finding reported by Nguyen et al 62 showed that the structure of activated carbon was not homogeneous.…”

High quality activated carbon was successfully produced from Tectona grandis sawdust by chemical activation using potassium chloride and sodium thiosulphate in a ratio of 1:1.5:1. Surface characterization of sawdust and activated carbon showed the presence of several functional groups such as hydroxyl, ketones, phenols, carboxylic acids, aldehydes and aryl halide together with the heterogeneous surface and extensive porous network as depicted by morphological characterization. It was found that the per cent yield by mass of Tectona grandis sawdust was 52% (SD ± 0.41%). The content of fixed carbon (67.3%) and volatile matter (13.7%) in T. grandis sawdust signifies the ease with which it can be ignited and oxidized. The x‐ray diffraction analysis of activated carbon prepared from T. grandis sawdust indicated amorphous behavior of activated carbon. In the present work, activated carbon possesses 8.76 pH zero‐point charge, 1270 m2/g BET surface area, 0.673 cm3/g total pore volume and 0.42 g/cm3 bulk density.

Activated carbon (AC) derived from coconut shells (CS-AC) was obtained through pyrolysis at 700℃ and subsequently activated with H3PO4. AC was ground in a Wiley mill several times to form powder particles at particle scales of 80, 100, and 200 meshes. The characterization of the AC was studied using scanning electron microscopy (SEM), X-ray diffraction analysis (XRD), Fourier-transform infrared spectroscopy (FT-IR), and surface area analysis (SBET). The CS-AC-200 mesh resulted in a higher percentage of mesopores and surface area. This particle size had a larger surface area with angular, irregular, and crushed shapes in the SEM view. The smaller particles had smoother surfaces, less wear, and increased curing depth and ratio of the hardness of the resin composite. Based on the characterization results of the AC, it is evident that CS-AC with a 200 mesh particle size has the potential to be used as a filler in biocomposites.
